OVERVIEW

Premium Arcweld 7018-1 Stick Electrodes for Structural Integrity

The Arcweld 7018-1 Stick Electrode (3.2mm) is a high-performance consumable designed for professional welders who demand reliability and superior mechanical properties in their welds. As an E7018-1 classified electrode, this product is engineered to provide exceptional impact toughness even at sub-zero temperatures, making it a preferred choice for critical structural applications, bridges, and pressure vessels where safety standards are paramount.

One of the standout features of this electrode is its Moisture Resistant (MR) coating. In the world of low-hydrogen welding, moisture is the enemy, leading to hydrogen-induced cracking and porosity. The Arcweld 7018-1 is formulated to resist moisture pick-up, ensuring that your welds remain sound and free from defects, provided proper storage and handling procedures are followed. This makes it an excellent choice for job sites where environmental control can be challenging.

Welders will appreciate the smooth operating characteristics of the Arcweld 7018-1. It delivers a stable arc with minimal spatter, which translates to less post-weld cleanup and grinding. The slag system is designed to cover the weld bead completely, protecting it as it cools, yet it detaches easily—often curling up on its own. Whether you are welding in the flat, horizontal, vertical, or overhead positions, this electrode offers excellent puddle control and bead appearance.

At Josef Gas, we understand the importance of using the right filler metal for the job. The Arcweld 7018-1 3.2mm electrode strikes the perfect balance between deposition rate and versatility, suitable for medium-to-heavy plate thicknesses. It is optimized for DC+ (Direct Current Electrode Positive) polarity, ensuring deep penetration and fusion.

Typical Applications

  • Structural steel fabrication (beams, columns)
  • Pressure vessel and boiler construction
  • Heavy equipment repair and maintenance
  • Shipbuilding and offshore structures

FAQ

The main difference is impact toughness. E7018-1 electrodes are tested to provide specific impact properties (Charpy V-Notch) at lower temperatures (usually -45°C) compared to standard E7018 electrodes (usually -29°C), making them suitable for more critical applications.

Yes, once the hermetically sealed packaging is opened, E7018-1 low-hydrogen rods should be stored in a rod oven at temperatures typically between 250°F and 300°F to prevent moisture absorption.

Arcweld 7018-1 is designed primarily for DC+ (Direct Current Electrode Positive) polarity. While some 7018 rods can run on AC, DC+ generally provides smoother arc characteristics and better penetration.

The typical operating range for a 3.2mm (1/8") E7018 electrode is between 110 and 150 amps, depending on the position and base metal thickness.

No, E7018 electrodes are designed for vertical-up welding. The slag is too heavy and fluid to support a vertical-down technique, which would lead to slag entrapment.

MR stands for 'Moisture Resistant'. This indicates the coating is formulated to resist absorbing moisture from the air longer than standard coatings, reducing the risk of hydrogen cracking.

E7018-1 is a low-hydrogen rod and generally requires cleaner steel than cellulosic rods like E6010 or E6011. For best results and to prevent porosity, oil, grease, rust, and paint should be removed from the weld area.
